PCR diagnostic of asymptomatic FV3 infected adult frogs that died following bacterial stimulation.

open access: yes, 2014
PCR was performed on DNA extracted from spleen (Spl), liver (Liv) and kidneys (Kid) of a representative of frogs that died 15, 18 or 29 days after bacterial stimulation (45, 48 or 59 dpi, respectively) using primers specific for FV3 MCP, vDNA poly II and

Moisture‐Flux‐Sensitive Convection Strengthens MJO Preconditioning

open access: yesGeophysical Research Letters, Volume 53, Issue 10, 28 May 2026.
Abstract Despite decades of research, the Madden‐Julian Oscillation (MJO) remains challenging for global prediction systems, partly because its representation is sensitive to convection‐environment interactions. We evaluate a new prognostic convective closure in NOAA's Unified Forecast System (UFS) that incorporates large‐scale moisture‐flux ...

Enhancing Great Plains Nocturnal Precipitation and Low‐Level Jets in AM4 With an Extended CLUBB Closure

open access: yesJournal of Advances in Modeling Earth Systems, Volume 18, Issue 5, May 2026.
Abstract In this study, we extend the Cloud Layers Unified by Binormals (CLUBB) turbulence scheme within the GFDL atmospheric model (AM4) by implementing direct momentum‐flux prognosis and a multiscale turbulent lengthscale, to improve the simulation of nocturnal precipitation and associated Low‐Level Jets (LLJs) over the Great Plains (GP). Toward this

Progress Towards Integrating the Finite-Volume Cubed-Sphere (FV3) Dynamical Core Tangent Linear and Adjoint Models into JEDI [PDF]

open access: yes, 2018
The Joint Effort for Data assimilation Integration (JEDI) -- led by the Joint Center for Satellite Data Assimilation (JCSDA) -- is an inter-organizational endeavor to develop a common framework for performing data assimilation.

Capability Demonstration of a JEDI‐Based System for TEMPO Assimilation: System Description and Evaluation

open access: yesJournal of Advances in Modeling Earth Systems, Volume 18, Issue 5, May 2026.
Abstract The launch of the Tropospheric Emissions: Monitoring of Pollution (TEMPO) mission in 2023 marked a new era in air quality monitoring by providing high‐frequency, geostationary observations of column NO2 across most of North America. In this study, we present the first implementation of a TEMPO NO2 data assimilation system using the Joint ...

Chicamocha canyon wind energy potential and VAWT airfoil selection through CFD modeling

open access: yesRevista Facultad de Ingeniería Universidad de Antioquia, 2020
The use of vertical axis wind turbines (VAWT) in Colombia could tackle the energy distribution difficulties as large parts of the territory are not connected to the electrical grid.

Response of the Italian agile frog (Rana latastei) to a Ranavirus, frog virus 3: a model for viral emergence in naïve populations. [PDF]

open access: yes, 2004
Ranavirus (family Iridoviridae) is a genus of pathogens of poikilotherms, and some ranaviruses may play a role in widespread mortality of amphibians. Ecology of viral transmission in amphibians is poorly known but can be addressed through experimentation

Amphibian (Xenopus laevis) Interleukin-8 (CXCL8): A Perspective on the Evolutionary Divergence of Granulocyte Chemotaxis

open access: yesFrontiers in Immunology, 2018
The glutamic acid-leucine-arginine (ELR) motif is a hallmark feature shared by mammalian inflammatory CXC chemokines such the granulocyte chemo-attractant CXCL8 (interleukin-8, IL-8). By contrast, most teleost fish inflammatory chemokines lack this motif.
